这只发生在我的一台机器上.我认为这是一个环境配置问题.所有机器都运行ESET Smart Security软件防火墙.有任何想法吗？

using System;
using System.Net;
using System.Diagnostics;
using System.Threading;

namespace Test
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            bool exit = false;
            WebClient wc = new WebClient();
            DateTime before = DateTime.Now;
            wc.DownloadStringAsync(new Uri("http://74.125.95.147"), "First"); // IP Address of google, so DNS requests don't add to time.
            wc.DownloadStringCompleted += delegate(object sender, DownloadStringCompletedEventArgs e)
            {
                Debug.WriteLine(e.UserState + " Call: " + (DateTime.Now - before));

                if ((string)e.UserState == "First")
                {
                    before = DateTime.Now;
                    wc.DownloadStringAsync(new Uri("http://74.125.95.147"), "Second");
                }
                else …
